We fit this model to all the Swift-RXTE datasets. Guided by
previous low/hard state data ([1]}; GDP08), we fix the
radius of the irradiated portion of the inner disc at \(1.1\times R_{d}\) . Fig. REF  shows the evolution of the source
parameters in this model. The top panel gives the bolometric flux,
which varies by an order of magnitude. This is dominated by the hard
X-ray component, whose spectral photon index (second panel) decreases
from 1.8 to 1.6 during the first section of the decline, and then
stabilizes at this value hereafter. The source did not make a
transition to the high/soft or even intermediate state, but remained
in the hard state throughout the outburst.
